Once surface particles like dirt, dust, and fingerprints have been addressed using the standard removal process, any remaining deep stains or discoloration require a more targeted approach. This is where BASWA Clean comes in.

What Is BASWA Clean?

BASWA Clean is a two-part surface cleaner engineered specifically for use with all BASWA acoustical plaster finishes. Rather than relying on scrubbing or abrasive chemicals that could damage the porous surface, BASWA Clean works by penetrating deep into the surface pores. It emulsifies oils, makes stains soluble in water, and lifts both stains and odors through oxidation, restoring the original white appearance of your BASWA installation.

Sustainability is built into the formula. After it does its job, BASWA Clean breaks down into water and oxygen, making it fully biodegradable and environmentally safe.
